To provide a page turning system that can efficiently turn pages particularly sheets of music with a simple device and mechanism and that has a consecutive concurrent field of view in which the sheet before and after the one currently being played can be looked at in advance of the turning of the sheet.

As a first means, in order to bring out to the maximum the action of a finger having the simplest and the best function for turning over pages, a round finger hole for the turning is prepared correspondingly to the cup-like bulb of a finger as a through-hole of a leaflet, in an easy-to-turn position of pages, wherein the cup-like bulb of the finger is applied to the edge of the hole to turn over the pages in a hooking manner. As a second means, in sheets of music folded like a screen of four or more sheets on one side, the four page portion of the sheets of music is spread under a concurrent visual field and, after completion of playing for the first two pages, the further pages are turned over, with a convenient timing selected during the playing of the third and fourth pages. The turning of the pages is done by picking the center peak part of the four page portion and feeding to the pile 11 of sheets on the left, which simultaneously brings out the consecutive sheets of music from the pile 12 of sheets on the right under a concurrent visual field.
